  • Immutable Form. The guardian stela is immune to any spell or effect that would alter its form, and it treats critical hits against it as normal hits.
  • Sacred Link. A guardian stela can perform a ritual taking 1 hour to attune itself to another creature. Once it has done so, the linked creature becomes more watchful, gaining a +1 bonus on Wisdom (Perception) checks and initiative rolls. It receives warnings from the guardian stela’s alarm spells and can pass freely through an arcane lock created by the guardian stela. If the linked creature takes damage while within 30 feet of the guardian stela, as a reaction can either cast hellish rebuke on the creature that damaged its linked creature or else the guardian stela can take half of that damage instead of the linked creature. A creature that fails its saving throw against the guardian stela’s hex deals an extra 1d6 necrotic damage whenever the linked creature hits it with an attack. A creature cannot be linked to more than one guardian stela.
  • Watchful Guardian. The guardian stela can see invisible creatures and adds double its proficiency bonus on Wisdom (Perception) checks and on Dexterity saving throws. If the guardian stela spends at least 1 hour adjacent to a portal or opening, it can cast arcane lock on it. This arcane lock remains in place until dispelled or until the guardian stela moves away from it for more than 1 hour.
  • Innate Spellcasting. The guardian’s spellcasting ability is Charisma (spell save DC 12). It can innately cast the following spells, requiring no material components: At will: counterspell, hex, magic circle 3/day each: alarm, hellish rebuke, unseen servant 1/day each: telekinesis


  • Slam. Melee Weapon Attack: -2 to hit, reach 5 ft., one target. Hit: 1 bludgeoning damage.


Common stelae are monuments fashioned by Mesoamerican cultures, typically carved from stone in relief but sometimes embellished with brightly colored paints, turquoise, or precious metals and inscribed with mask-like faces or entire bodies to honor great lords or priests. Guardian stelae are imbued with mystic power to serve as sacred guardians for those within the temples, monuments, or palaces they protect. They may be carved in the likeness of the one they protect or created in their honor to protect others.
